Or "Why Do All Photo Editors Suck?"

Similar to a previous post, the above is a screenshot showing a RAW preview and an exported JPG of inferior quality - only this time, it's in Adobe Lightroom.

Isn't the point of a photo editor to tweak photos to the point that they're "perfect"?  If what I'm seeing in the editor is not what I'm going to actually get, the thing is utterly useless.

So, apologies to Canon, I guess - it's not DPP necessarily, it's probably everything.

Question: Why is it so impossible to simply get a JPG that looks identical to a RAW preview.

If it's not impossible, what hoops do I have to jump through (and, just as importantly, why)?
